What is the data type of Variant? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Variant is a special data type that has no type declaration characters, can change the type dynamically at run time, and supports all simple data types such as integer, floating point, string, Boolean, date-time, currency, and OLE automation objects.

Variant adaptability

You can replace any data type with a Variant data type, which makes it more adaptive. If the content of a Variant variable is a number, it can be represented as a string or its actual value, depending on the context, for example:

Dim MyVar As Variant

MyVar = 98052

In the previous example, there is an actual value of 98052 in MyVar. As expected, arithmetic operators can operate on Variant variables that contain numeric values or string data that can be interpreted as numeric values. If you use the + operator to add MyVar to other variables of numeric Variant or numeric types, the result is an arithmetic sum.

The Empty value is used to mark Variant variables that have not been initialized (given an initial value). A Variant containing Empty represents 0 in the context of a numeric value, or a zero-length string ("") if used in the context of a string.

Empty should not be confused with Null. Null means that the Variant variable does contain an invalid data.

In Variant, Error is a special value used to indicate when an error occurs during a procedure. However, unlike other types of errors, programs do not produce normal application-level error handling. This allows the programmer, or the application itself, to take additional action based on this error value. You can use the CVErr function to convert real numbers into incorrect values to produce Error values.

After reading the above, have you mastered the method of what the data type of Variant is? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
